When using the API you can only backup loaded registry files. [Only the current user&#8217;s registry NTUSER.DAT file is loaded, and so only it is backed up. -MM]<\/p>\n<p>Tweaking.com &#8211; Registry Backup uses the volume shadow copy service instead. This allows perfect backups of the registry files and all profiles on the system.<\/p>\n<p>&#8230;<\/p>\n<p>Quote From Microsoft:<\/p>\n<blockquote><p>&#8220;Applications that back up or restore system state including system files and registry hives should use the Volume Shadow Copy Service instead of the registry functions.&#8221;<\/p>\n<p>&#8220;Using <code>RegSaveKey<\/code> together with <code>RegRestoreKey<\/code> to copy subtrees in the registry is not recommended. This method does not trigger notifications and can invalidate handles used by other applications.&#8221;<\/p><\/blockquote>\n<p>By using the Volume Shadow Copy instead of the <code>RegSaveKey<\/code> API this registry backup program is safer to use.<\/p><\/blockquote>\n<p>Is Tweaking.com Registry Backup <em>really<\/em> safer than ERUNT, as its author claims? I&#8217;m not sure i *want* to trigger those notifications when i&#8217;m backing up the registry. That&#8217;s nobody&#8217;s business, right? But what about that &#8220;invalidate handles used by other applications&#8221;? I can see that might be a problem when *restoring* using <code>RegRestoreKey<\/code>&#8211;maybe that doesnt trigger the handle. But on save? Who needs to see that? Or is Micro$oft just trying to make sure *their* digital eyes see everything, even saves?<\/p>\n<p>On the 2nd issue, the backing up of other users registry files is valid, ERUNT even says so. <a title=\"http:\/\/www.larshederer.homepage.t-online.de\/erunt\/erunt.txt\" href=\"http:\/\/www.larshederer.homepage.t-online.de\/erunt\/erunt.txt\" target=\"_blank\">http:\/\/www.larshederer.homepage.t-online.de\/erunt\/erunt.txt<\/a><\/p>\n<hr \/>\n<hr \/>\n<h2>References<\/h2>\n<p><a title=\"http:\/\/www.techsupportalert.com\/how_to_backup_the_windows_registry.htm\" href=\"http:\/\/www.techsupportalert.com\/how_to_backup_the_windows_registry.htm\" target=\"_blank\">How to Backup the Windows Registry<\/a> at <a title=\"Gizmo's freeware techsupportalert.com\" href=\"https:\/\/montgomeryminds.com\/blog\/program-uninstallers-programs-that-uninstall-other-programs\/\" target=\"_blank\">techsupportalert.com<\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Backing up the Registry is important, especially if you&#8217;re going to try a Controversial Registry Cleaner.
